Although many plant families in Thailand are listed in the global IUCN Red List, Thailand need to set up conservation monitoring of rare to update. This project had the objectives of assessing the threat and conservation status of indigenous plant species. Since its establishment in 2002, the project assessment provides an important practical mechanism for implementation of Global Strategy for Plant Conservation of the conservation for Biological Diversity. The projects directly contributed to target 2 of the strategy, for assessments status of plants. Department of National Parks, Wildlife and Plant Conservation, Thailand, is committed to undertaking a global assessment of the conservation status of plant species. We are confident that this publication marks a major milestone in Thailand’s quest to manage and conserve threatened plant species, and that it will be use to resource and conservation managers.

FOREWORD


The checklist has been based on several publication of plants in Thailand, especially the Flora of Thailand, which have been investigated by both foreign and Thai botanists.

We thank to the BKF staff of the Forest Herbarium for their helps in many ways.

Finally, we would like to express thanks to Director General of the Department of National Parks, Wildlife and Plant Conservation for supporting the work and publishing this list.

The present checklist was compiled at the Forest Herbarium (BKF), Bangkok, as a assessment on the threatened plants of Thailand. The data for originated from many sources of information such as flora of Thailand volumes already published, a preliminary check-list of Threatened plants in Thailand (Pooma, 2005) and specimens database of BKF. The assessment of threatened plant in Thailand (phase II) were carried out from October 2011– September 2015. Objective of the project is to assessment of threatened plant in Thailand base on the IUCN (International Union for Conservation of Nature and Natural Resources) and for surveying and collecting rare, threatened, new record and new species of plants in Thailand. They were assessed by GeoCAT program (Geospatial Conservation Assessment Tool) of Royal Botanical Garden, Kew, United Kingdom and IUCN Red List Categories (version: 3.1. 2001).

The calculation for the Extent of Occurrence (EOO) follows the IUCN Red List guidelines. In the calculation of Area of Occupancy (AOO), we have used a 2 x 2 km. grid (area of 4 sq. km.). The values for EOO and AOO were generated using GeoCAT program.

This work is solid work to catalogue plant species for which conservation is a concern in the country. The list can be used to provide information on the conservation status individual species; guide the listing of individual species in national or international legislation; aid in conservation planning and priority setting; help to identify priority species for conservation action and recovery planning and support education programs.

INTRODUCTION


The threatened plants list is based on IUCN version 1994 for endemic and rare species, and version 2001 for vulnerable and endangered species. The list is divided into four main groups: pteridophytes, gymnosperms, monocotyledons and dicotyledons. The list also includes geographical and ecological distributions of each species. One thousand four hundred and forty two species are listed nine hundred and forty species are classified as 715 vulnerable species, 207 endangered species and 18 species are critically endangered.
